An experimental study of phenol and o-cresol reactive extraction using sulf
uric acid salts of trioctylamine, via emulsion liquid membrane is presented
. The effects of carrier concentration and of the volume ratio of phases we
re investigated. Two models, one proposed by Chaudhury and Pyle (1992) and
the second proposed by Yan (1993) were tested. The model predictions are in
good agreement with the experimental data. (C) 1999 Elsevier Science Ltd.
